Scotland centre Matt Scott will miss the rest of this season's RBS 6 Nations Championship due to injury.
Scott, who has won 34 caps, suffered an elbow injury during Edinburgh's Guinness PRO12 game against Connacht last Friday.
And the Scottish Rugby Union said that an MRI scan carried out earlier this week has confirmed ligament damage in the joint.
The SRU said: "An MRI scan at Spire Murrayfield Hospital on Monday confirmed that Scott sustained elbow ligament damage in his club's Guinness PRO12 loss to Connacht on Friday.
"Further examination this Friday will confirm if the player requires surgery on the joint.
"However, it is clear at this stage that he will at least miss the remainder of the 2016 RBS 6 Nations, and will return to his club for ongoing care and assessment."
Scott started Scotland's Six Nations opener against England at Murrayfield last month, but Mark Bennett and Duncan Taylor forged the midfield partnership when Scotland beat Italy 36-20 in Rome 11 days ago.
Scotland continue their Six Nations campaign on Sunday when France visit Edinburgh, with their final match being against Ireland in Dublin on Saturday week.
